I disassembled the top end of my XR400R this week getting ready for the machine work I have planned. When I took the valve cover off and removed the cam I found that the cam saddles had what looks like scuffing. The saddles are still smooth and you can't catch your fingernail on any of the scuff marks. Does this look like it's acceptable to continue running the head. Just looking for opinions. I have included some pics. I'm taking the head to the machine shop tomorrow to drop off for a valve job so I'll be able to ask machinist as well. Thanks.
